Technical Reports
Approximately one million Mg of broiler litter were generated in conjunction with Arkansas' 1989 broiler production. Common practices for disposal of the waste have the potential to damage the quality of downstream rivers and lakes. This possibility is enhanced due to the concentration of broiler production in areas of the state with shallow soils, steep slopes, and limited suitable disposal area. Since the risk of pollution is greatest immediately following disposal and increases with rainfall depth and intensity, adverse water quality impacts may be mitigated by timing the application to coincide with low probability of surface losses of the nutrients …

I am highly honored to be invited to present the 3rd annual S.H. Phillips Distinguished Lecture on No-Tillage Agriculture. My interest and subsequent research efforts in the area of no-tillage agriculture began in 1969. Shirley Phillips encouraged my efforts through his interest and enthusiasm for this rather radical and new approach to farming without the use of tillage equipment. At that time, Harry Young, a western Kentucky farmer and pioneer of no-tillage agriculture along with Shirley, Jim Herron, Charlie Slack and other co-workers were excited about the potential of this new, innovative farming system and what it could do for …
